Look, Frances, in my post to which you replied, nowhere did I mention 'left christian folks.' Rakesh's post (to which I replied) didn't say anything about 'left christian folks' either. Nor were they referred to in the NYT article both of us were commenting on.
I think I already made my thoughts on serious religious leftists clear when I wrote of Mark Stansbery as a quite admirable example of such leftists (in the post entitled 'Consuming Religion').
What's clear, however, is that serious left-wing religious people are a very small minority in this country, perhaps as small as or even smaller than the serious secular Left (such as it is).
